The minimum duration until a measured value is assessed as stable is the
monitored time interval. The actual duration is mostly longer.

Measuring the temperature
For reproducible ORP measurements, it is essential to measure the temperature of the test sample.
You have the following options to measure the temperature:
 Automatic measurement of the temperature with the temperature sensor
(NTC 30 or Pt 1000) integrated in electrode.
 Measurement by an external temperature sensor.
 Manual determination and input of the temperature.
The measuring instrument recognizes whether a suitable sensor is connected
and automatically switches on the temperature measurement.
The display of the temperature indicates the active temperature measuring
mode:

If you wish to measure (or calibrate) without temperature sensor, proceed as
follows:
1.
Measure the current temperature of the test sample.
2.
Set the temperature value with <><>.
or
In the <MENU/ENTER>/U/Man. temperature menu, set the temperature value with <><>.

ORP calibration
ORP electrodes are not calibrated. You can, however, check ORP
electrodes by measuring the ORP of a test solution and comparing
the value with the nominal value.
